:mw/Ewan the hoop is formed. Hoops made of hot .cold rolled in this manner show that stretch i f ing of the hoops after being applied to the barrel, which ordinarily occurs when the barrel Iis handled is entirely prevented and overcome, and a. hoop of increased strength and durability is obtained.

'The advantages o' my invention will be apparent tov those skilled in the art.. By subjecting the material from which the hoops are made to a cold rolling operation,

the stretch is taken out of the metal before beading. and forming the hoops, so that when later applied to the barrels the hoops will not elongate or stretch while in service. In this Way hoops are provided which will remain in place on the barrel and which will not become loosened when the key or barrel to i which they are applied is frequently handled. l

The manner of beading the hoops and the size of the hoops obviously may be varied and the beads may be omitted Without departing from my invention and other metal to length and fastening one end of the cut lengths to the other to form the hoop.

2. In the manufacture oi metal hoops, the steps consisting in. stretching hot rolled metal strips beyond the elastic limit of the metal, cutting the stretched metal to length and fastening one end of the eut lengths to the other to form the hoop.
